- May be worse on one side than others
- Sometimes accompanied by a bulge on the back
- Screen may still function normally
Likely causes
- CommonAdhesive seal aging or weakeningThe glue holding the screen to the frame degrades over years of heat and use.
- CommonSwelling battery pushing the screen looseAn aging or damaged battery can expand and force the screen away from the frame.
- PossibleFrame bent from a dropImpact can warp the metal frame enough to leave a visible gap.
What to do
- Check the back of the phone for any bulging, which points to a swollen battery and needs prompt attention.
- Stop charging the phone and avoid pressing on the gap if you see any bulging.
- If there's no bulging, the gap is more likely adhesive wear and less urgent, but water resistance may be compromised.
- Avoid using the phone near water or in rain until the seal is repaired, since the seal likely no longer works.
- Back up your data and get the screen professionally reseated or the battery replaced.
